To answer this question, you need to understand SQL (Structured Query Language) and the basic syntax used to extract data from a database.
The correct answer is A) SELECT.
Option A) SELECT - This option is correct because the SELECT statement is used to retrieve data from a database. It allows you to specify the columns you want to retrieve and the table(s) from which you want to retrieve the data. The SELECT statement is one of the fundamental statements in SQL and is used in almost every query.
Option B) GET - This option is incorrect because there is no GET statement in SQL for extracting data from a database. The GET statement is not a standard SQL statement.
Option C) OPEN - This option is incorrect because the OPEN statement is not used to extract data from a database. The OPEN statement is typically used to open a cursor in SQL, which is used to fetch rows from a result set.
Option D) EXTRACT - This option is incorrect because the EXTRACT statement is not used to extract data from a database. The EXTRACT statement is used to extract specific parts (such as year, month, day, etc.) from a date or time value in SQL.
Therefore, the correct answer is A) SELECT. This option is correct because the SELECT statement is used to extract data from a database.
